The potential commercialization of neuronal replacement therapy using smart polymers
(Massachusetts Institute of Technology, 2005)
NeuroBioChip Device is a programmable, biocompatible, biodegradable, polymer matrix which allows the growth and programming of donor neurons. It creates a microenvironment conducive for neuronal outgrowth and promises a ...
Conditional dynamics of non-Markovian, infinite-server queues
(Massachusetts Institute of Technology, 2005)
We study the transient dynamics of a partially observed, infinite server queue fed with a Poisson arrival process whose controlled rate is changed at discrete points in time. More specifically, we define a state that ...
Glycocalyx acting as a mechanotransducer of fluid shear stress
(Massachusetts Institute of Technology, 2005)
It is widely recognized that fluid shearing forces acting on endothelial cells (ECs) have a profound effect on EC morphology, structure and function. Recent investigations in vivo have indicated the presence of a thick ...
Momentum and scalar transport in vegetated shear flows
(Massachusetts Institute of Technology, 2005)
Environmental aquatic flows are seldom free of vegetative influence. However, the impact of submerged vegetation on the hydrodynamics and mixing processes in aquatic flows remains poorly understood. In this thesis, I present ...
A continuum theory with long-range forces for solids
(Massachusetts Institute of Technology, 2005)
A non-local integral-type continuum theory, introduced by Silling [61] as peridynamic theory, is analyzed. The theory differs from classical (local) continuum theories in that it involves long-range forces that act between ...
SIP : a smart digital image processing library
(Massachusetts Institute of Technology, 2005)
The Smart Image Processing (SIP) library was developed to provide automated real-time digital image processing functions on camera phones with integer microprocessors. Many of the functions are not available on commercial ...
Cell modulated DC/DC converter
(Massachusetts Institute of Technology, 2005)
A very high frequency converter roughly based on a class E topology is investigated for replacing a conventional boost converter circuit. The loss mechanisms in class E inverters are characterized, and metrics are developed ...
Using a gimbal to calibrate an inertial measurement unit
(Massachusetts Institute of Technology, 2005)
In this thesis, an inertial measurement unit (IMU) consisting of 3 accelerometers and 3 rate gyros is created using off-the-shelf sensors from STMicro and Analog Devices. A novel technique for calibrating the orientation, ...
A study of seismoelectric signals in measurement while drilling
(Massachusetts Institute of Technology, 2005)
An LWD acoustic wave can move the excess charge in the electric double layer along the borehole wall to generate a streaming electric field. This thesis is an experimental and theoretical investigation of the electric field ...
Development of new parameters for structure determination and dynamic investigations on biomacromolecules by NMR
(Massachusetts Institute of Technology, 2005)
Nuclear magnetic resonance (NMR) spectroscopy is unique in the content of structural as well as dynamic information that it can provide at atomic resolution. The aim of this PhD-thesis was to contribute to the understanding ...
